We currently have a wild card certificate in our Exchange invironment. However, is it best to use a specific certicate for ADFS such fs01.domain.com? And if Clustering Load Balance is being used, would it also be best to incorporate the cluster name in the Certificate? or would our current wild card cert be sufficient?

Well, wildcart cert is definitely sufficient for anything, that you're using inside of your domain, because anything actually has a name of *.domain.com.

But I prefer (due to security measures) to use a separate cert for every server. For example for Exchange I'd use 1 cert, that includes Exchange internal and external URLs, NLB DNS name and autodiscover URLs. You don't really need to have  mailbox server names in the cert. This answers your first and third question: yes, it's better to use separate certs for every service (due to security requirements, for example if you need to recall one of the certs you don't need to replace it everywhere); and yes, I'd recommend to incorporate cluster name into the certificate (if this cluster is used for the same service, that requires this cert), though I wouldn't do it if cluster is for ADFS and cert is for Exchange.

With ADFS there is ADFS farm which requires ADFS service name which will be get published on internet
You can use same wildcard certificate on ADFS server as long as ADFS service name FQDN match the one in certificate.
If you have multiple ADFS servers in adfs farm, No matter which certificate you use, you need to export same certificate with private key on one adfs server and need to import it on another ADFS servers and ADFS proxy servers if any.
